EDWIN A. REEVES, OF MILFORD, CONNECTICUT.

VACUUM CLEANER.

Application filed April 15, 1920.

To all whom it may concern:

Be it known that I, EDWIN A. REEvEs, a citizen of the United States, residing at MiL ford, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Vacuum Cleaners, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention has particular reference to new and useful improvements in vacuum cleaners of the manually operated type. It is the object of this invention, among other things, to so design and construct the vacuum cleaner that it may be economically constructed and most efficient in its operation.

To these and other ends, my invention consists of the vacuum cleaner having certain details of construction and combina tions of parts as will be more particularly described and pointed out in the claims.

Referring to the drawings Figure 1 is an elevation of my improved vacuum cleaner complete; and

Figure 2 is an enlarged sectional view of a portion thereof taken upon line 22 of Figure 1.

The cleaner illustrated herein is of the type shown in United States Letters Patent No. 1,093,473 issued to me April 14, 1914i, and in brief consists of a body having two cylinders, a vacuum cylinder 10 and a piston cylinder 11, these being separably secured together, and within the latter is a piston that is operated by a handle 12 that passes through the cylinder head 13. Upon the lower end of the vacuum cylinder 10 is a plurality of threads or corrugation 14. The conical head 15 is formed with a cylindrical band 16 at its upper end, that is turned inwardly upon itself to form an inner band 17 with both bands being provided with threads or corrugations similar to those designated 1 1. Secured to the conical head 15 and projecting therethrough is a nozzle tube 18 upon which is the nozzle 23. The dust bag 19 is closed at its upper end 20 and fixed at its lower end by any preferred means to an open ended sleeve 21, having a collar 22 thereon provided with threads or corrugations 24, similar to those above described.

All of the threads or corrugations above described are of substantially the same pitch Serial 1T0. 374,115.

and shape and being formed preferably in sheet metal, are produced at the very minimum cost. In assembling the parts the collar 22 is threaded into the inner band 17 and then the conical head 15 secured in the vacuum cylinder 10 by engagement of the threads of the band 16 with the threads or corrugations 14-. If desired the inner band 17 may be omitted and the collar 22 threaded into the inside of the band 16.

Minor changes and alterations may be made within my invention aside from those herein suggested, and I would therefore have it understood that I do not limit myself to the exact construction herein shown, but claim all that falls fairly within the spirit and scope of the appended claims.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is:

1. The combination in a vacuum cleaner, of a dust bag, a receptacle having threads or corrugations'a-t one end thereof; a head having a cylindrical portion and an inner band concentric therewith, both said cylindrical portion and inner band being threaded, the latter being threaded within the open end of said dust bag, and threadably engaging the thread upon the inside of said inner band. i

2. In a vacuum cleaner, the combination with a receptacle internally threaded at one:

end; of a head having a cylindrical portion at one end turned over upon itself to fornr an inner concentric hand, both said cylindrical portion and-inner concentric band being threaded; a dust bag; and a sleeve fixed to the open end thereof threadably secured to said inner band.

3. In a vacuum cleaner, the combination with a receptacle internally threaded at one end; of a head having a cylindrical portion at one end turned over upon itself to form an inner concentric band, both said cylindrical portion and inner concentric band being threaded; a dust bag; and a sleeve having a threaded collar thereon, fixed to the open end thereof threadably secured to said inner band.

In testimony whereof, I have hereunto affixed my signature.

EDWIN A. REEVES.
